GASO'LINE FILTM.

Application 1ed pril 25, 1928-. Serial No. 634,447.

To all whom z't may concern Be it known that I, FRANK A. BEnNnEELD, a citizen of the United States, residing at Ada, in the county of Norman'and State of Minnesota, have invented certain new and useful Improvements in Gasoline Filters, of which the following is a specification.

In carrying out the prese-nt invention, 1t is my purpose to provide a filter for gasollne adapted to be installed in the gasoline feed line between the storage tank and carburetor of a motor, for absolutely preventing the entrance of dirt, water or other foreign matter into the carburetor.

A further purpose of the invention is the revision of such a gasoline filter that may he readily installed in set posltion, and one that will edectively o erate underI all conditions, the invention eing further characterized by its simplicity of construction, eciency and durability, and that may be manufactured and marketed at relatively small cost.

The nature and advantages. of the 1nvention will be better understood when the following detailed description is read 1n connection with the accompanying drawings, the invention residing in the construction,combination, and arrangement of parts as claimed.

in the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a vertical sectional view of my improved lter, and

Figure 2 is a transverse section taken approximately on line 2-2 of Fig-.ure 1.

Referring to the drawings in etail, my

l filter comprises among other elements, an

elongated 'open ended cylindrical casing 5, externally screw threaded at its opposite ends, and carrying upper and lower cap members 6 and 7, respectively. Between the members 6 and 7 and the opposite ends of the casing 5 are packing rings 8.

The lower cap member 7 is-equipped with a pet cock 9 for permitting of the draining of the filter, while the upper cap member 6 is formed with an outlet neck 10, into which is screw threaded one end of an elbow 11, the opposite end of this elbow being coupled at 12 to a gas pipe 13 that rends to the carburetor of a motor veabove said screen 18 is a fiat-like cross rod 19, that is provided with a central opening for permitting of the passage therethrough of a guide rod 20, formed upon the lower end of a fioat 21. The nature of this float is such las to swing to the position shown in Figure 1, in the presence of gasoline or to rise in the presence of water, the upper-end of this fioat carrying a valve rod 22, that is equipped with a ball valve 23, and adapted to impinge against a seat 24 in the top cap 6, Jfor consequently preventing the discharge of the gasoline from the filter when the fioat rises upwardly in the presence of water.

The top ca 6 is provided internally with a sleeve 25, t at surrounds the seat 24 and effects a guide for the valve 23, this sleeve being provided with openings 26 for olovious purposes. The lower end of the sleeve 25 is externally screw threaded for receiving an internally screw threaded fiange 27 of a valve rod guide sleeve 28, the lower.y

end of which is flared outwardly at 29, as clearly shown in Figure 1.

In view of the above description, it will at once be apparent that when the gasoline within the filter is free from water, the fioat 21 will be in the position shown in Figure 1 for permitting of the 'discharge of the gasoline from the filter, it being of course also understood that in view of the presence of the lter screen 18 any sediment or foreign matter within the gasoline will be prevented from entering the carburetor. Should water accumulate within the filter, the Hoat 21 will continually rise for closing-the outlet of the casing and consequently cutting od the supply of gasoline to the carburetor, at which time, the pet cock may be opened for draining the water therefrom.

The advantages of a device of this character will be readily appreciatedv by those skilled in the art, and even though l have herein shown and described the preferred embodiment of my invention, it is nevertheless to be understoodV Ythat minor clmm'ges may be made therein without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent is Apparatus for separating water from aso'lme comprising a, casing provided at lts top with a fluid outlet opening and at its lower portion with a, fluid inlet opening, a float member located in the casing between said openings and adapted to move vertically in the caslng2 the specific gravity of the float member being such that it will float upon water and sink in gasoline, a nipple depending from the outlet o ning and 1provided at its side and below t e top of t e casing with openin s, a ro'd passing centrallyV through the oat, means for guiding the lower portion of the rod, and a ball mounted upon the upper end of the rod and guided in the nipple and adapted to moveacross the openm s in the sides of the nipples and adapted to seat upon the outlet opening of the casing. f

In testimony whereof I aix my signa.- ture. i
